OK, if you want to go all the way back to roots, then I can take 
logic back to Frege and Peirce, giving it more like 120 years than 
60. I was dating it from the deployment of CLASSIC, which I think of 
as the first real DL. The papers you cite are prehistory for DLs, not 

BTW, I did a Google search and the earliest date I can find 
associated with the term is 1996, at a workshop that you helped 
organize. So OK, I should have said 15 years, not a decade.

I am surprised to hear that Bell wasn't the dominant player, though. 
I guess I associate Ron, you, Alex and and Deb all with DLs at Bell, 
and have always though of that as something of an axis. Where would 
you locate the dominant players? (Genuine question)
